PAUL ORIOLLE, OF NANTES, FRANCE.

AUTOMATIC FIRE-EXTINGUISHER.

SPECIFIGATIGN forming part of Letters Patent No. 252,501, dated January 17, 1882.

Application lcd October 5, 1581. (No model.) Patented in France March 15, 1881. 1

To all whom it may concern Be it known that I, PAUL ORIOLLE, ofN antes,

France, engineer, have invented a System of Automatc.Fire-EXtinguisher, known as Oriolles Automatic Extinguisher and I do hereby declare that the t'ollowin g is a full, clear, and

exact description ofthe same, reference being had to the annexed sheets ol'drawings, making a part of the same. u

The present invention has for its object au apparatus which automatically attacks a fire immediately 4on the breaking out ot' same. This apparatnsis caused to act by the slightest abnormal rise of temperature, and consequently operates so as to extinguish the tire at the very beginning. The principle of the apparatus is based on the use of fusible substances at low temperatures for closing the ori lices of pressure water-pipes, so that the fusion of such substances causes the opening of the pipe, and thus creates a continual projection of liquid.

The accompanying drawings serve to illustrate the arrangement I have invented for putting into practice the said principle.

Figure l is a vertical section of the extinguisher. ,Figa 2 is a plan of same. Fig. 3 is On its end is screwed a piece, g, which supports an end View of the fusible connec'tionfrod.

In the different drawings the same `letters of reference indicate the same parts.

a isthe pipc,connected with the pressure-main.

the `connection rod o. Inside said pipe is `screwed a cap, which divides the jet of water under pressure. This cap is covered by a lid, b, which rests on au elastic Washer, and is kept pressed against the piece g by the screw d, to

which the rod c acts as a fixed ndt. The/rod ness caused by the hole which receives the pin fand the great conducting power of the latter produce the destruction of the rod c always at the same point, when theV latter is vbrought to the temperature which produces the fusion of the material of which it is composed. The piece g is provided with a shield,h,whch pro tects from the heat the lid b and the elastic washer which insures the tightness ot' thejoint with the pieceg at the side opposite the fusible rod c.

These apparatus should be situated at the points where the temperature is likely to become the soonest raised, and a-s soon as the tem perature becomes sufficiently high to cause the fusion of the rod e the screw d ceases to press on the lid b, which will be thrown back,as well as the rod c, bythe water undr pressure, which will be forced in all directions through the perforations in the cap t', and thus, by attacking immediately the re, will generally succeed in p extinguishing it.

I claim- The combination, with the iid b and pipe a,

of t-he piece g, screwed on the end of pipe, the

nut-rod c, carrying the screw d, and the fusible rod e, carrying therein a heat-conductor, f, as and for the purpose specitied.
